Abstract

An apparatus for user interfaces is described to measure inductively the deformation of a body (1) comprising at least two laminar conductive elements (3, 4), at least one of which is an AC energized inductor (4), wherein deformation causes relative axial movement between the at least two laminar elements (3, 4) and the maximum deformation distance is limited to prevent damage.
